Ash and co. accidentally wander onto a property under surveillance by the police, where they meet a Luxray and its trainer, a young brash, overeager Officer Jenny in training named Marble. A theft is set to occur so Ash and his friends decide to help catch the burglars, while also helping Marble, who is having trouble getting her Luxray to listen to her or get its Electric-type attacks to work properly. Things take a dangerous turn when everyone gets lost in the tunnels under the mansion.
Tropes
- Call-Back: Marble is stated to be a protege of the Officer Jenny from Mahogany Town, who acted similarly in her appearance.
- Jerk with a Heart of Gold: "Jerk" is a strong word for it. Marble isn't a jerk, so much as just obnoxious and brash, and she cares deeply for her Luxray.
- Running Gag: Someone comes up with a theory regarding the burglary and Marble insists that she was just about to say that.
